Struct Labels 

pub struct Labels(/* private fields */);

Structured key-value metadata based on BTreeMap.

Iteration order is stable because labels are stored in key order.

Example

use solti_model::Labels;

let mut labels = Labels::new();
labels.insert("zone", "eu");
labels.insert("gpu", "h100");

assert_eq!(labels.get("zone"), Some("eu"));
assert!(labels.contains_key("gpu"));

Implementations

impl Labels

pub fn new() -> Self

Creates an empty label map.

Example

use solti_model::Labels;

let labels = Labels::new();
assert!(labels.is_empty());

pub fn len(&self) -> usize

Returns the number of labels.

pub fn is_empty(&self) -> bool

Returns whether the map is empty.

pub fn insert<K, V>(&mut self, key: K, val: V) -> &mut Self

where K: Into<String>, V: Into<String>,

Inserts or replaces a label.

Example

use solti_model::Labels;

let mut labels = Labels::new();
labels.insert("tier", "dev").insert("tier", "prod");

assert_eq!(labels.get("tier"), Some("prod"));

pub fn get(&self, key: &str) -> Option<&str>

Returns the value for a key.

pub fn contains_key(&self, key: &str) -> bool

Returns whether a key exists.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

Iterates over labels in key order.

Example

use solti_model::Labels;

let mut labels = Labels::new();
labels.insert("b", "2");
labels.insert("a", "1");

let pairs: Vec<_> = labels.iter().collect();
assert_eq!(pairs, vec![("a", "1"), ("b", "2")]);

pub fn validate(&self) -> ModelResult<()>

Validates every label.

Errors

Returns crate::ModelError::Invalid.

Trait Implementations

impl Clone for Labels

fn clone(&self) -> Labels

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Labels

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Labels

fn default() -> Labels

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Labels

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Labels

impl<'a> IntoIterator for &'a Labels

type Item = (&'a str, &'a str)

The type of the elements being iterated over.

type IntoIter = LabelsIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl JsonSchema for Labels

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Labels

fn eq(&self, other: &Labels) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Labels

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
